ABSTRACT
Although irri gation with wastewater is in itse1f an effective form of wastewater treatment (such as in slow-rate land treatment), some degree of treatment must be provided to untreated municipal wastewater before it can be used for agricultural or landscape irrigation. The degree of preapplication treatment is an important factor in the planning, design, and management of wastewater irrigation systems. The purpose of this chapter is to describe briefly (a) the principal processes used to achieve the various degrees of preapplication treatment and (b) the quality of the effluents produced. The information provided is intended primarily for those not familiar with muni ci pal wastewater treatment or the characteristics of wastewater before and after treatment.
